To all whom it ma/y concern Beit known that I, Emmons Manner, of Marion,in the county of Wayne, and State of New York, have invented a newanduseful Improvement on Apparatus for Staying or Holding Doors inposition when open; and I do .hereby declare that the following is afull and exact description of the construction .and operation of thesame, reference being had to the accompanying drawings, making apart ofthis specification, in which- Figurel is a perspective view,representing the apparatus attached to the door.

Figure 2 is a sectional view, showing the parts detached.

Similar letters of reference indicate corresponding parts in eachfigure.

Figure 3,l the parts together, showing their movements.

The nature of my invention consists of a lever with a pivoted bearing inthe centre, and from which centre project the two parallel arms whichengage with a spiral springconnected by means of an upright bolt passingthrough it, the upper end of which is fitted loosely in a hole through ahorizontal projection on the upper end of a plate attached to the door,so that the lower end of the bolt may vibrate sufeiently to depress andraise the end of the lever the required distance', it being kept inposition by working in a. hole through the centre of a pivotedcross-'piece bearing on the ends of 4the arms ofA the lever, therebyforming a knuckle-joint, operated by pressing down the lever, and heldin position by the spiral spring, whereby the door, when open,

'uay be held in any desired position.

I construct my door-stay of malleable cast-iron, or other suitablematerial.

At each end of the vertical plate B, I make horizontal projections, thelower one of which forms the bearing for one of the two pivots on thecentre of the lever D. The other pivot works in a hole in the uprightpart of the plate.

The lever D has its bearing on the centre, working on transverse pivots,and the end that engages with the door is bent down and covered withIndia rubber, E, for the purpose of preventing injury to the floor orcarpet, and convenience of operation with the boot.'

.The other end is bent up for the same purpose.

On the centre ofthe lever, I attach two vertical arms, F F, extendingtoabout half the length of the plate B, and on Athe ends of these arms,I prepare bearingsv for the pivoted cross-piece G, upon which the spiralspring H rests, being kept in position by a bolt,

I, the upperfend ofwhich is tted loosely in a hole in the upperprojection J of the -plate B, the lower endworking in a hole in thecentre of the cross-piece G'. Near the upper end of this bolt, I attacha collar for the end of the spring to bear against. The workingparts areprotected from injury by the casing A.

When I use my door-stay, I attach it to the lower part of the door, asrepresented at iig. l. I then place the foot upon the lower part of' thelever, and press it down, which operation throws the arms lF F out ofperpendicular, thereby causing the spiral spring to act.

directly upon that side of the lever, pressing the rubbercoated end Eagainst the floor.

For closing the door, or changing its position, the operation isreversed, and the upper end of the lever is pressed down, which -throwsthe arms slightly out of line on that side, or enough so to secure thelever in position, which is accomplished by attaohin g a stop, K, to theside of the plate B.

Having thus described my invention, What I claim, and desire to secureby. Letters Patent, is-

The transverse lever D, provided with arms F F, in combination with theplate B, spiral spring H, bolt I, cross-piece J, and stop K, all beingconstructed substantially as herein represented, for the purpose setforth.

EMMONS MANLEY.
